ANTICORROSIVE IAIRRIAL.

- Ho Drawing.

My invention relates to an anti-rust or anticorrosive material, and consists of petrolatum with which has been incorporated basic or neutral zinc chromate.

6 This composition of matter may conslstof from 95% to 99% of petrolatum with whlch has been incorporated, by grinding very finely in a paint mill, from 1% to of basic or neutral zinc ehromate. 4

Inasmuch as the composition may soften under the summer sun and is likely to run, there may be added to the petrolatum hardening materials having-a higher melting point than petrolatum;

As a specific example, there may be added to the petrolatum 5% of 136 paraflin; or of white bees-wax; or of carnauba wax. Other waxes having higher melting points than petrolatum will answer the same 2 pur ose.

T e principal virtue of the composition is that it prevents after corrosion usually noticed in gun and rifle barrels where corrosion is likely to occur after anti-corrosive 7 Application filed Kay 8, 1985. Serial 10. 28,950.

grease is applied. The compound above de- 2 scribed will entirely prevent further corrosion.

I claim:

1. A composition of :matter comprisin petrolatum with which is finely incorporateg zinc 'chromate.

2. A composition according to claim 1 in which the proportion of petrolatum is from 95% to 99%, and the proportion of zinc chromate from 1% to 5%. I

3. A composition of matter consisting of petrolatum and a wax of higher melting point than petrolatum, with which is finely incorporated zinc chromate.

4. A composition according to claim 3 in. 9 which theproportion of zinc chromate is from 1% to 5%.

5. A composition according to claim 3 in which the proportion of wax is from 5% to 25% of the petrolatum.

In testimony whereof, I aflix my signature.
